How I Gained It: Almost a decade in sales/project management led to longer work hours, less exercise and an under-active thyroid. The stress of working 60 to 70 hours per week sent my cortisol levels on an up-and-down roller coaster. I easily gained 100 pounds in eight years.
Breaking Point: When I had to buy a size 44/30 pair of jeans, I knew I was unhealthy. I suffered from a fatty liver condition, low testosterone (which ruined my sex life for a while) and high cholesterol, and I was pre-diabetic.
